Target details

Function: Probably participates in establishing action potential waveform and excitability of neuronal and muscle tissues. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium, as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. Can be blocked by extracellular barium or cesium.Tissue specificity: Heart, brain, placenta, lung, skeletal muscle, and kidney. Diffusely distributed throughout the brain.Subcellular location: Membrane, Multi-pass membrane protein. Involvement in disease: Defects in KCNJ2 are the cause of long QT syndrome type 7 (LQT7), also called Andersen syndrome or Andersen cardiodysrhythmic periodic paralysis. Long QT syndromes are heart disorders characterized by a prolonged QT interval on the ECG and polymorphic ventricular arrhythmias. They cause syncope and sudden death in response to excercise or emotional stress. LQT7 manifests itself as a clinical triad consisting of potassium-sensitive periodic paralysis, ventricular ectopy and dysmorphic features. Defects in KCNJ2 are the cause of short QT syndrome type 3 (SQT3). Short QT syndromes are heart disorders characterized by idiopathic persistently and uniformly short QT interval on ECG in the absence of structural heart disease in affected individuals. They cause syncope and sudden death. SQT3 has a unique ECG phenotype characterized by asymmetrical T waves. Also known as: Inward rectifier potassium channel 2, Potassium channel, inwardly rectifying subfamily J member 2, Inward rectifier K(+) channel Kir2.1, Cardiac inward rectifier potassium channel, IRK1.

Handling

Handling

Reconstitute in 100 µL of sterile water. Centrifuge to remove any insoluble material.

Handling Advice

Avoid freeze and thaw cycles.

Storage

4 °C/-20 °C

Storage Comment

Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.
